Working in Confined Space Safety

What is a Confined Space?
A confined space is any area that is large enough for a worker to enter but has limited entry/exit points and is not designed for continuous occupancy (e.g., tanks, silos, pits, manholes, tunnels).

Hazards in Confined Spaces

  • Oxygen deficiency or enrichment

  • Toxic gases, fumes, or dust

  • Risk of fire or explosion

  • Restricted movement and visibility

  • Engulfment from liquids or loose materials

Safety Precautions

  1. Permit-to-Work System

    • Always obtain a Confined Space Entry Permit before starting work.

    • Ensure authorization from a competent person.

  2. Atmospheric Testing

    • Test for oxygen levels, flammable gases, and toxic vapors.

    • Use continuous monitoring devices.

  3. Ventilation & Lighting

    • Provide adequate forced ventilation.

    • Use explosion-proof lighting when necessary.

  4. Personal Protective Equipment (PPE)

    • Wear helmets, gloves, safety shoes, and protective clothing.

    • Use respirators or breathing apparatus when required.

  5. Communication & Supervision

    • Maintain constant communication between entrants and attendants.

    • Assign a standby person outside the confined space.

  6. Emergency Preparedness

    • Have rescue equipment (tripods, lifelines, harnesses) ready.

    • Train workers in confined space rescue and first aid.
